具体实施方式
下面将结合附图,对本申请中的技术方案进行描述。
图1是适用于本申请实施例的通信系统100的架构示意图。如图1所示,该通信系统包括多个终端(如图1中的101、102、103)与至少一个无线接入网设备(如图1中的104),其中,多个终端之间可以直接进行通信,并且多个终端可以与无线接入网设备进行通信。
无线接入网设备是终端通过无线方式接入到通信系统中的接入设备。无线接入网设备可以是基站(base station)、演进型基站(evolved NodeB,eNodeB)、发送接收点(transmission reception point,TRP)、第五代(5th generation,5G)移动通信系统中的下一代基站(next generation NodeB,gNB)、第六代(6th generation,6G)移动通信系统中的下一代基站、未来移动通信系统中的基站或WiFi系统中的接入节点等;也可以是完成基站部分功能的模块或单元,例如,可以是集中式单元(central unit,CU),也可以是分布式单元(distributed unit,DU)。本申请的实施例对无线 接入网设备所采用的具体技术和具体设备形态不做限定。在本申请中,无线接入网设备简称网络设备,如果无特殊说明,在本申请中,网络设备均指无线接入网设备。
终端是具有无线收发功能的设备,可以向网络设备发送信号,或接收来自网络设备的信号。终端也可以称为终端设备、用户设备(user equipment,UE)、移动台、移动终端等。终端可以广泛应用于各种架构,例如,设备到设备(device-to-device,D2D)、车物(vehicle to everything,V2X)通信、机器类通信(machine-type communication,MTC)、物联网(internet of things,IOT)、虚拟现实、增强现实、工业控制、自动驾驶、远程医疗、智能电网、智能家具、智能办公、智能穿戴、智能交通、智慧城市等。终端可以是手机、平板电脑、带无线收发功能的电脑、可穿戴设备、车辆、飞机、轮船、机器人、机械臂、智能家居设备等。本申请的实施例对终端所采用的具体技术和具体设备形态不做限定。
网络设备和终端可以是固定位置的,也可以是可移动的。网络设备和终端可以部署在陆地上,包括室内或室外、手持或车载;也可以部署在水面上;还可以部署在飞机、气球和人造卫星上。本申请的实施例对网络设备和终端的应用场景不做限定。
在本申请的实施例中,网络设备的功能也可以由网络设备中的模块(如芯片)来执行,也可以由包含有网络设备功能的控制子系统来执行。这里的包含有网络设备功能的控制子系统可以是智能电网、工业控制、智能交通、智慧城市等上述应用架构中的控制中心。终端的功能也可以由终端中的模块(如芯片或调制解调器)来执行,也可以由包含有终端功能的装置来执行。
图1所示的通信系统可以支持如图2所示的通信架构,在该架构下,终端(例如,终端101)可以通过至少一个中继与网络设备(例如,网络设备104)进行通信,在这种情况下,终端与网络设备之间存在至少两条通信链路,一条链路为终端与网络设备之间的空口链路,这条链路之外的其他链路为终端通过中继与网络设备进行通信的中继链路,每个中继对应一条中继链路,中继链路包括终端与中继之间的链路以及中继与网络设备之间的空口链路,图2中仅示出了一个中继(例如,终端102)。为了便于描述,将终端101与网络设备之间的空口链路称为第一通信链路,将终端101通过中继与网络设备之间建立的中继链路称为第二通信链路。空口链路可以理解为:终端与网络设备之间的直连链路,也可以称为“Uu链路”。本申请实施例中的中继可以理解为:具备中继能力的设备、如终端、模块、芯片等,在此不做限定。
然而,在通信过程中,网络设备可能会根据终端上报的终端与网络设备之间的通信链路的测量结果或中继上报的中继与网络设备之间的通信链路的测量结果,触发终端或中继由当前连接的网络设备切换至另一网络设备,例如,网络设备根据终端上报的终端与网络设备之间的通信链路的测量结果,触发终端从当前连接的网络设备切换到另一网络设备,在这种情况下,由于中继仍然保持与原先的网络设备的连接,这将导致中继不再能够为终端提供中继服务,或者,网络设备根据中继上报的中继与网络设备之间的通信链路的测量结果,触发中继从当前连接的网络设备切换到另一网络设备,在这种情况下,由于终端仍然保持与原先的网络设备的连接,这将导致终端不再能够通过中继获得中继服务。
有鉴于此,本申请实施例提供了一种通信方法,在网络设备需要触发终端进行网络设备的切换时,或者,在网络设备触发中继进行网络设备的切换时,网络设备将终端与中继从源网络设备切换至目标网络设备,从而避免中继服务的中断。
在本申请中,可以将图2所示的通信架构称为UE aggregation通信架构,在该架构下,中继与终端之间可以通过第三代合作伙伴计划(3rd generation partnership project,3GPP)定义的通信链路建立连接,例如,侧行链路((sidelink,SL)),或者,可以通过非3GPP定义的有线或者无线通信链路建立连接,如光纤、WiFi、蓝牙等。
以下,基于图2所示的通信架构,结合图3、图4,对本申请的实施例提供的通信方法进行详细说明。
图3示出了本申请实施例提供的一例通信方法300的示意性流程图。下面,对方法300的每个步骤进行详细说明。
步骤301,第一网络设备(例如,图1、图2中的网络设备104)向第一终端(例如,图1、图2中的终端101)发送第一配置信息,第一配置信息指示第一终端对第一通信链路的信号质量 进行测量,和/或,第一网络设备向第二终端(例如,图1、图2中的终端102)发送第二配置信息,第二配置信息指示第二终端对第二通信链路中的第二终端与第一网络设备之间的通信链路的信号质量进行测量。
在一种实现方式中,第一网络设备可以向第一终端发送第一配置信息,并且向第二终端发送第二配置信息,通过第一配置信息指示第一终端对第一通信链路的信号质量进行测量,通过第二配置信息指示第二终端对第二终端与第一网络设备之间的通信链路的信号质量进行测量。
在另一种实现方式中,第一终端可以向第一网络设备上报第一终端的第三信息,第三信息包括第一终端的节能需求和/或当前剩余电量,第二终端可以向第一网络设备上报第二终端的第四信息,第四信息包括第二终端的节能需求和/或当前剩余电量,第一网络设备根据第三信息和/或第四信息,向第一终端发送第一配置信息,或者,向第二终端发送第二配置信息。
例如,相对于第二终端,第一终端的节能需求较低或者当前剩余电量较高,在这种情况下,第一网络设备可以仅向第一终端发送第一配置信息,或者,相对于第一终端,第二终端的节能需求较低或者当前剩余电量较高,在这种情况下,第一网络设备可以仅向第二终端发送第二配置信息。
例如,如果第一网络设备只获取到了第一终端的节能需求和/或当前剩余电量,或者,只获取到了第二终端的节能需求和/或当前剩余电量,则第一网络设备可以仅向第一终端发送第一配置信息或者仅向第二终端发送第二配置信息。
步骤302,第一终端根据第一配置信息,向第一网络设备发送第一测量结果;和/或,第二终端根据第二配置信息,向第一网络设备发送第二测量结果。
第一终端根据第一配置信息,对第一通信链路的信号质量进行测量,得到第一测量结果,之后向第一网络设备发送第一测量结果,和/或,第二终端根据第二配置信息,对第二通信链路中的第二终端与第一网络设备之间的通信链路的信号质量进行测量,得到第二测量结果,之后向第一网络设备发送第二测量结果。
第一测量结果可以包括第一通信链路的质量。
第二测量结果可以包括第二通信链路中的第二终端与第一网络设备之间的空口链路的质量。
需要说明的是,步骤302还可以替换为:第一终端向第一网络设备发送第一测量结果;和/或,第二终端向第一网络设备发送第二测量结果。在这种情况下,方法300可以不包括步骤301,换句话说,步骤301为可选地的步骤。
换句话说,第一终端可以不依赖于第一配置信息对第一通信链路的信号质量进行测量,和/或,第二终端可以不依赖于第二配置信息对第二终端与第一网络设备之间的通信链路的信号质量进行测量,例如,第一终端可以根据预定义的配置信息对第一通信链路的信号质量进行测量,和/或,第二终端可以根据预定义的配置信息对第二终端与第一网络设备之间的通信链路的信号质量进行测量。
步骤303,第一网络设备根据来自第一终端的第一测量结果和/或来自第二终端的第二测量结果,确定第二网络设备。
情况1,第一网络设备仅接收到了来自第一终端的第一测量结果,例如,第一测量结果指示第一通信链路的信号质量较差,在这种情况下,为了避免中继服务的中断,第一网络设备决定将第一终端与第二终端切换至第二网络设备。
情况2,第一网络设备仅接收到了来自第二终端的第二测量结果,例如,第二测量结果指示第二终端与第一网络设备之间的通信链路的信号质量较差,在这种情况下,为了避免中继服务的中断,第一网络设备决定将第一终端与第二终端切换至第二网络设备。
情况3,第一网络设备接收到了来自第一终端的第一测量结果与第二终端的第二测量结果,例如,第一测量结果指示第一通信链路的信号质量较差,和/或,第二测量结果指示第二终端与第一网络设备之间的通信链路的信号质量较差,在这种情况下,为了避免中继服务的中断,第一网络设备决定将第一终端与第二终端切换至第二网络设备。
步骤305,第一网络设备向第二网络设备发送请求消息,请求消息指示将第一终端与第二终端由第一网络设备切换至第二网络设备。
在一种实现方式中,第一网络设备可以针对第一终端、第二终端分别发送一条请求消息,针对第一终端的第一请求消息指示将第一终端由第一网络设备切换至第二网络设备或指示将第一终端由第一网络设备切换至第二网络设备的第一小区,针对第二终端的第二请求消息指示将第二终端由第一网络设备切换至第二网络设备或指示将第二终端由第一网络设备切换至第二网络设备的第二小区。其中,第一小区和第二小区可以是第二网络设备下地同一小区,或者,也可以是第二网络设备下的不同小区。
在另一种实现方式中,第一网络设备可以针对第一终端、第二终端分别发送一条请求消息,针对第一终端的第一请求消息指示将第一终端由第一网络设备切换至第二网络设备或指示将第一终端由第一网络设备切换至第二网络设备的第一小区,第一请求消息携带第二终端的标识,针对第二终端的第二请求消息指示将第二终端由第一网络设备切换至第二网络设备或指示将第二终端由第一网络设备切换至第二网络设备的第二小区,第二请求消息携带第一终端的标识。
在再一种实现方式中,第一网络设备可以针对第一终端、第二终端分别发送一条请求消息,针对第一终端的第一请求消息指示将第一终端由第一网络设备切换至第二网络设备或指示将第一终端由第一网络设备切换至第二网络设备的第一小区,第一请求消息携带第二终端的标识,且指示第一终端是使用中继服务的终端和/或第二终端是提供中继服务的终端,第二请求消息指示将第二终端由第一网络设备切换至第二网络设备或指示将第一终端由第一网络设备切换至第二网络设备的第二小区,第二请求消息携带所述第一终端的标识,且指示第一终端是使用中继服务的终端和/或第二终端是提供中继服务的终端。
在再一种实现方式中,第一网络设备可以针对第一终端、第二终端共发送一条请求消息,该请求消息指示将第一终端切换至第二网络设备或指示将第一终端由第一网络设备切换至第二网络设备的第一小区,并且指示将第二终端切换至第二网络设备或指示将第二终端由第一网络设备切换至第二网络设备的第二小区,在这种情况下,请求消息可以携带第一终端的标识或第二终端的标识,并指示第一终端是使用中继服务的终端和/或第二终端是提供中继服务的终端。
上述第一终端的标识可以为第一网络设备为第一终端分配的用于标识第一终端的标识、第一网络设备为第一终端分配的用于在第一网络设备与第二网络设备之间的Xn口上唯一标识第一终端的XnAP ID中的任意一种。
上述第二终端的标识可以为第二终端的小区无线网络临时标识(cell-radio network temporary identifier,C-RNTI)、第一网络设备为第二终端分配的用于标识第二终端的标识、第一网络设备为第二终端分配的用于在第一网络设备与第二网络设备之间的Xn口上唯一标识第二终端的XnAP ID中的任意一种。
步骤306,第二网络设备向第一网络设备发送请求接受消息,请求接受消息可以指示第一终端在第二网络设备下的配置和/或第二终端在第二网络设备下的配置。本申请实施例中的“请求接受消息”也可以称为“请求确认消息”。
如果请求消息包括第一请求消息与第二请求消息,在这种情况下,第一请求消息与第二请求消息可能同时到达第二网络设备,或者,可能一前一后到达第二网络设备,第二网络设备通常需要等到接收到两条请求消息后才会进行下一步的决策。
假设第二网络设备首先接收到了第一请求消息,在这种情况下,第二网络设备可以根据第一请求消息中携带的第二终端的标识,确定需要等待针对第二终端的请求消息,在接收到针对第二终端的请求消息后,再进行下一步的决策。
或者,假设第二网络设备首先接收到了第二请求消息,在这种情况下,第二网络设备可以根据第二请求消息中携带的第一终端的标识,确定需要等待针对第一终端的请求消息,在接收到针对第一终端的请求消息后,再进行下一步的决策。
所谓进行下一步的决策,可以理解为:第二网络设备在接收到针对终端的请求消息后,对该终端执行准入控制,即,判断该终端是否可以接入第二网络设备,若可以接入,则第二网络设备生成该终端连接至第二网络设备所需要的配置信息,之后,向第一网络设备发送该终端连接至第二网络设备所需要的配置信息。
例如,第二网络设备在接收到了第一请求消息与第二请求消息后,对第一请求消息对应的第 一终端与第二请求消息对应的第二终端执行准入控制,即,判断第一终端和第二终端是否可以接入第二网络设备,若可以接入,则第二网络设备生成使用中继服务的第一终端连接至第二网络设备所需要的配置信息,并生成提供中继服务的第二终端连接至第二网络设备所需要的配置信息,之后,第二网络设备将配置信息发送至第一网络设备,即,第二网络设备可以向第一网络设备发送请求接受消息,请求接受消息指示第一终端在第二网络设备下的配置与第二终端在第二网络设备下的配置。
在一种实现方式中,第二网络设备可以针对第一终端、第二终端分别向第一网络设备发送一条请求接受消息,例如,第二网络设备针对第一终端,向第一网络设备发送第一请求接受消息,针对第二终端,向第一网络设备发送第二请求接受消息,第一请求接受消息携带第三配置信息,第三配置信息指示第一终端在第二网络设备下的配置,第二请求接受消息携带第四配置信息,第四配置信息指示第二终端在第二网络设备下的配置。
在另一种实现方式中,第二网络设备可以针对第一终端、第二终端共发送一条请求接受消息,在这种情况下,请求接受消息可以携带上述第三配置信息与第四配置信息。
为了防止第二网络设备在接收到其中一条请求消息后,无限制等待另一条请求消息,第二网络设备在接收到其中一条请求消息后,如果在第一时间长度内接收到了另一条请求消息,则第二网络设备可以对第一终端与第二终端执行准入控制,并在确定第一终端与第二终端可以接入第二网络设备的情况下,生成使用中继服务的第一终端连接至第二网络设备所需要的配置信息,以及提供中继服务的第二终端连接至第二网络设备所需要的配置信息;如果在第一时间长度内未接收到另一条请求消息,则第二网络设备可以仅对接收到的请求消息对应的终端执行准入控制,并在确定接收到的请求消息对应的终端可以接入第二网络设备的情况下,生成接收到的请求消息对应的终端连接至第二网络设备所需要的配置信息。
例如,第二网络设备首先接收到了第一请求消息,根据第一请求消息中携带的第二终端的标识,确定需要等待针对第二终端的请求消息,之后,第二网络设备可以启动定时器,定时器的时长为第一时间长度,如果第二网络设备在定时器超时时仍未接收到第二请求消息,则第二网络设备可以仅对第一终端执行准入控制,在确定第一终端可以接入第二网络设备的情况下,生成第一终端连接至第二网络设备所需要的配置信息,并向第一网络设备发送针对第一终端的请求接受消息,该请求接受消息携带第一终端连接至第二网络设备所需要的配置信息。
步骤307,第一网络设备向第一终端发送第三配置信息,和/或,向第二终端发送第四配置信息。
示例性的,第一网络设备可以通过针对第一终端的第三无线资源控制(radio resource control,RRC)重配置消息将第三配置信息发送至第一终端,和/或,第一网络设备可以通过针对第二终端的第四RRC重配置消息将第四配置信息发送至第二终端。
步骤308,第一终端根据第三配置信息,接入第二网络设备,和/或,第二终端根据第四配置信息,接入第二网络设备。
例如,第一终端根据第三配置信息,接入第二网络设备或接入第二网络设备的第一小区,和/或,第二终端根据第四配置信息,接入第二网络设备或接入第二网络设备的第二小区。其中,第一小区和第二小区可以是第二网络设备下地同一小区,或者,也可以是第二网络设备下的不同小区。
步骤309,第一终端向第二网络设备发送第三配置完成消息,和/或,第二终端向第二网络设备发送第四配置完成消息。
示例性的,第一终端可以通过针对第二网络设备的第三RRC重配置完成消息将第三配置完成信息发送至第二网络设备,和/或,第二终端可以通过针对第二网络设备的第四RRC重配置完成消息将第四配置完成消息发送至第二网络设备。
为了避免当第一终端通过第二终端向第二网络设备发送数据时,由于第二终端尚未完成中继数据的配置,因此不能对该数据进行转发的情况,在一种实现方式中,第二终端可以在完成中继数据的配置后,指示第一终端可以通过第二终端进行上行传输,在这种情况下,方法300还可以包括步骤310:第二终端向第一终端发送第三指示信息,第三指示信息指示第一终端通过第二终 端进行上行传输。
需要说明的是,第二终端可以在接收到第三配置信息后向第一终端发送第三指示信息,换句话说,步骤310可以在步骤307之后执行。
本申请实施例中的“指示第一终端可以通过第二终端进行上行传输”也可以替换成以下描述:指示第二终端已完成中继配置,或者,指示第二终端为第一终端提供中继服务。在另一种实现方式中,第二网络设备可以在接收到来自第二终端的第四配置完成消息后,指示第一终端可以通过第二终端进行上行传输,在这种情况下,方法300还可以包括步骤311:第二网络设备向第一终端发送第四指示信息,第四指示信息指示第一终端通过第二终端进行上行传输。
在另一种实现方式中,第一网络设备可以先向第二终端发送第四配置信息,在接收到来自第二终端的第四配置完成消息后,再向第一终端发送第三配置信息,在该方式中,由于已经预先确保第二终端已经接入第二网络设备,因此,第一终端可以在接入第二网络设备后,随时可以通过第二终端进行上行传输。
在另一种实现方式中,第一网络设备可以先向第二终端发送第四配置信息,并在发送第四配置信息一段时间后,再向第一终端发送第三配置信息,发送第四配置信息的时刻和发送第三配置信息的时刻之间的间隔可以由第一网络设备决定。
可选地,作为一种实现方式,方法300在步骤305之前还可以包括步骤304,第一网络设备确定第一终端、第二终端支持切换至同一网络设备。

例如,第一终端可以在确定自己与第二终端之间存在绑定或者配对关系的情况下,向第一网络设备发送第一指示信息,和/或,第二终端可以在确定自己与第一终端之间存在绑定或者配对关系的情况下,向第一网络设备发送第二指示信息。所述绑定或者配对关系可以理解为,第一终端设备和第二终端设备之间可以建立连接或者已经存在连接,并且第一终端设备可以通过第二终端设备和网络设备之间进行数据传输。
例如,第一终端与第二终端是同一个设备上的两个终端,例如,一辆车上的两个摄像头,并且摄像头之间通过WiFi或者电缆等方式连接,这两个终端可以在初次开机时通过信息交互,确定彼此之间存在绑定或者配对关系,在该绑定关系中,假设第一终端为接收中继服务的终端,第二终端为提供中继服务的终端,在这种情况下,第一终端与第二终端可以确定各自支持与对方切换至同一网络设备,之后,第一终端可以向第一网络设备发送第一指示信息和/或第二终端可以向第一网络设备发送第二指示信息。
第一指示信息中可以携带第二终端的标识,或者,携带第二终端的标识与第一终端的标识,第一网络设备根据来自第一终端的第一指示信息中携带的第二终端的标识,或者,根据第一指示信息中携带的第二终端的标识与第一终端的标识,可以确定第一终端与第二终端支持切换至同一网络设备。
第二指示信息中可以携带第一终端的标识,或者,携带第一终端的标识与第二终端的标识,第一网络设备根据来自第二终端的第二指示信息中携带的第一终端的标识,或者,根据第二指示信息中携带的第二终端的标识与第一终端的标识可以确定第一终端与第二终端支持切换至同一网络设备。
在一种实现方式中,第一终端可以将第一指示信息和第一测量结果一起发送至第一网络设备,和/或,第二终端可以将第二指示信息和第二测量结果一起发送至第一网络设备。
在另一种实现方式中,第一指示信息可以通过终端能力上报流程上报基站,即第一终端向第一网络设备上报的终端能力信息(UE capability information)消息中包括第一指示信息,和/或,第二指示信息可以通过终端能力上报流程上报基站,即第二终端向第一网络设备上报的终端能力 信息消息中包括第二指示信息。
方式2
第一网络设备根据第一终端的第一信息和/或第二终端的第二信息,确定第一终端与第二终端支持切换至同一网络设备,其中,第一信息、第二信息来自核心网。
例如,核心网中存储有第一终端的第一信息和/或第二终端的第二信息,例如,第一信息中可以携带第二终端的标识,第二信息中可以携带第一终端的标识。
在一种实现方式中,第一网络设备可以在第一终端接入第一网络设备的过程中主动从核心网获取第一终端的第一信息,和/或,在第二终端接入第一网络设备的过程中主动从核心网获取第二终端的第二信息。
在另一种实现方式中,第一网络设备也可以在确定第一终端支持配置UE aggregation进行通信或支持与某个终端配对或绑定后和/或在确定第二终端支持为配置UE aggregation的终端提供中继服务或支持与某个终端配对或绑定后,再从核心网获取第一终端的第一信息和/或第二终端的第二信息(例如,向核心网发送请求查询第一终端的第一信息和第二终端的第二信息的消息),第一网络设备可以根据第一信息中携带的第二终端的标识,确定第一终端与第二终端支持切换至同一网络设备,和/或,根据第二信息中携带的第一终端的标识,确定第一终端与第二终端支持切换至同一网络设备。关于第一网络设备确定第一终端支持配置UE aggregation进行通信,第二终端支持为配置UE aggregation的第一终端提供中继服务的方法会在下文中进行介绍。
第一终端的第一信息可以是第一终端的订阅信息,第二终端的第二信息可以是第二终端的订阅信息。
在方式1与方式2中,上述各信息中携带的第一终端的标识可以是第一终端的C-RNTI或者S-TMSI或者第一网络设备为第一终端分配的用于标识第一终端的标识,第二终端的标识可以是第二终端的C-RNTI或者SAE临时移动用户标识(SAE-temporary mobile subscriber identifier,S-TMSI)或者第一网络设备为第二终端分配的用于标识第二终端的标识。
需要说明的是,在具体实现时,步骤304中的第一网络设备确定第一终端、第二终端支持切换至同一网络设备可以不是第一网络设备实际执行的步骤,例如,第一网络设备确定第一终端、第二终端支持切换至同一网络设备的动作可以理解为:第一网络设备获取相关信息,根据该相关信息向第二网络设备发送请求消息。
上述相关信息可以是第一指示信息、第二指示信息、第一信息、第二信息中的至少一种,关于第一网络设备获取第一指示信息、第二指示信息、第一信息、第二信息中的至少一种的方式请参考上述方式1与方式2中的相关描述,为了简洁,此处不再赘述。
还需要说明的是,在具体实现时,上述方式1与方式2可以单独实施,或者,也可以组合后实施,本申请实施例对此不作限定。
在本申请实施例中,来自第一终端的第一指示信息可以指示第一终端是使用中继服务的终端和/或第二终端是提供中继服务的终端,和/或,来自第二终端的第二指示信息可以指示第一终端是使用中继服务的终端和/或第二终端是提供中继服务的终端。
基于此,在步骤301中,第一网络设备可以根据第一指示信息和/或第二指示信息,向第一终端发送第一配置信息,或者,向第二终端发送第二配置信息。
例如,第一网络设备根据第一指示信息和/或第二指示信息,确定第一终端为使用中继服务的终端,和/或,确定第二终端是提供中继服务的终端,在这种情况下,第一网络设备可以仅向使用中继服务的终端,即第一终端发送第一配置信息,或者,仅向提供中继服务的终端,即第二终端发送第二配置信息。
在本申请实施例中,第一终端的第一信息可以指示第一终端是使用中继服务的终端和/或第二终端是提供中继服务的终端,和/或,第二终端的第二信息可以指示第一终端是使用中继服务的终端和/或第二终端是提供中继服务的终端。
基于此,在步骤301中,第一网络设备可以根据第一信息和/或第二信息,向第一终端发送第一配置信息,或者,向第二终端发送第二配置信息。
例如,第一网络设备根据第一信息和/或第二信息,确定第一终端为使用中继服务的终端,和 /或,确定第二终端是提供中继服务的终端,在这种情况下,第一网络设备可以仅向使用中继服务的终端,即第一终端发送第一配置信息,或者,仅向提供中继服务的终端,即第二终端发送第二配置信息。
值得一提的是,方法300是以第一终端通过一个中继(即,第二终端)与第一网络设备进行通信为例,对本申请实施例提供的通信方法介绍,但这并不构成对本申请实施例的限定,方法300同样适用于第一终端通过至少两个中继与第一网络设备进行通信的场景。
在该场景下,上述步骤305中的针对第一终端的请求消息中可以携带上述至少两个中继的标识,当第一网络设备针对上述各个中继向第二网络设备分别发送了一条请求消息时,第二网络设备可以根据针对第一终端的请求消息携带的至少两个中继的标识,确定需要等待针对该至少两个终端的请求消息,在接收到针对该至少两个终端的请求消息后,再进行下一步的决策。
可选地,作为一种实现方式,第一网络设备在执行步骤301之前,可以对第一终端与第二终端配置UE aggregation,通过配置UE aggregation,第一终端可以在通过第一通信链路和第一网络设备直接进行通信的同时,通过第二终端和第一网络设备之间建立第二通信链路,并通过第二通信链路和第一网络设备之间进行通信。
下面结合图4对第一网络设备对第一终端与第二终端作关于UE aggregation的配置的方法400进行介绍。方法400可以单独实施,或者,也可以与方法300组合实施。
步骤401,第一网络设备向第一终端发送第一RRC重配置消息,第一RRC重配置消息包括用于第一终端构建UE aggregation通信架构的配置信息。
例如,用于第一终端构建UE aggregation通信架构的配置信息可以包括空口链路的配置以及中继链路的配置,第一终端据此完成相应的配置。
可选地,作为一种实现方式,步骤301中的第一配置信息可以携带在第一RRC重配置消息中,例如,第一配置信息可以携带在第一RRC重配置消息的信元measconfig中。
步骤402,第一网络设备向第二终端发送第二RRC重配置消息,第二RRC重配置消息包括用于第二终端在向第一终端提供中继服务时所需要的配置信息。
在一种实现方式中,第一网络设备可以在确定第一终端支持配置UE aggregation进行通信,第二终端支持为配置UE aggregation的第一终端提供中继服务的情况下,通过第一RRC重配置消息向第一终端发送用于第一终端构建UE aggregation通信架构的配置信息,通过第二RRC重配置消息向第二终端发送第二终端在向第一终端提供中继服务时所需要的配置信息。
下面对第一网络设备确定第一终端支持配置UE aggregation进行通信,第二终端支持为配置UE aggregation的第一终端提供中继服务的方式进行介绍。
方式1
第一网络设备根据来自第一终端的指示信息和/或来自第二终端的指示信息,确定第一终端支持配置UE aggregation进行通信,第二终端支持为配置UE aggregation的第一终端提供中继服务。
例如,在第一终端、第二终端确定彼此之间存在绑定或者配对关系的情况下,第一终端可以确定自己支持构建UE aggregation通信架构,第二终端还可以确定自己支持在UE aggregation通信架构中为第一终端提供中继服务,之后,第一终端可以向第一网络设备指示第一终端支持配置UE aggregation进行通信,第二终端支持为配置UE aggregation的第一终端提供中继服务,和/或,第二终端还可以通过向第一网络设备指示第一终端支持配置UE aggregation进行通信,第二终端支持为配置UE aggregation的第一终端提供中继服务。关于第一终端、第二终端确定彼此之间存在绑定或者配对关系的方法请参考方法300中的相关描述,为了简洁,此处不再赘述。
第一网络设备根据第一终端和/或第二终端的指示,确定第一终端支持配置UE aggregation进行通信,第二终端支持为配置UE aggregation的第一终端提供中继服务。
例如,来自第一终端的指示信息中可以携带第二终端的标识,或者,携带第二终端的标识与第一终端的标识,第一网络设备根据来自第一终端的第一指示信息中携带的第二终端的标识,或者,根据第一指示信息中携带的第二终端的标识与第一终端的标识,可以确定第一终端支持配置UE aggregation进行通信,第二终端支持为配置UE aggregation的第一终端提供中继服务。
来自第二终端的指示信息中可以携带第一终端的标识,或者,携带第一终端的标识与第二终 端的标识,第一网络设备根据来自第二终端的第二指示信息中携带的第一终端的标识,或者,根据第二指示信息中携带的第二终端的标识与第一终端的标识,可以确定第一终端支持配置UE aggregation进行通信,第二终端支持为配置UE aggregation的第一终端提供中继服务。
上述来自第一终端的指示信息可以是方法300中的第一指示信息,或者,也可以是第一终端的终端能力信息等其他指示信息,上述来自第二终端的指示信息可以是方法300中的第二指示信息,或者,也可以是第二终端的终端能力信息等其他指示信息。
方式2
第一网络设备根据从核心网获取的第一终端的第一信息和/或第二终端的第二信息,确定第一终端支持配置UE aggregation进行通信,第二终端支持为配置UE aggregation的第一终端提供中继服务。
在另一种实现方式中,第一网络设备可以在接收到第一终端上报的第一终端周围的可以为第一终端提供中继服务的终端的标识后,从中选择至少一个终端作为第一终端的中继,例如,第一网络设备可以从核心网获取多个终端的授权信息,根据多个终端的授权信息,第一网络设备确定多个终端中的一个终端(例如,第一终端)可以支持构建UE aggregation通信架构,并且确定多个终端中的其他终端具备提供中继服务的能力,在这种情况下,第一网络设备可以指示第一终端上报第一终端周围的可以为第一终端提供中继服务的终端的标识,之后,第一网络设备可以在接收到第一终端上报的第一终端周围的可以为第一终端提供中继服务的终端的标识后,从中选择至少一个终端(例如,第二终端)作为第一终端的中继。
之后,第一网络设备可以通过第一RRC重配置消息向第一终端发送用于第一终端构建UE aggregation通信架构的配置信息,通过第二RRC重配置消息向第二终端发送第二终端在向第一终端提供中继服务时所需要的配置信息。
上述标识可以为终端的小区无线网络临时标识(cell-radio network temporary identifier,C-RNTI)、第一网络设备为该终端分配的用于标识该终端的标识。
可选地,作为一种实现方式,步骤301中的第二配置信息可以携带在第二RRC重配置消息中,例如,第二配置信息可以携带在第二RRC重配置消息的信元measconfig中。
上述信元measconfig中具体可以包括测量对象、测量上报配置、测量间隔(GAP)等信息。
步骤403,第一终端向第一网络设备发送第一RRC重配置完成消息。
第一终端在根据第一RRC重配置消息完成空口链路的配置以及中继链路的配置后,向第一网络设备发送第一RRC重配置完成消息。
可选地,作为一种实现方式,第一终端可以通过步骤403中的第一RRC重配置完成消息向第一网络设备发送方法300中的第一指示信息。
步骤404,第二终端向第一网络设备发送第二RRC重配置完成消息。
第二终端在根据第二RRC重配置消息完成向第一终端提供中继服务时所需要的配置后,向第一网络设备发送第二RRC重配置完成消息。
可选地,作为一种实现方式,第二终端可以通过步骤404中的第二RRC重配置完成消息向第一网络设备发送方法300中的第二指示信息。
为了避免当第一终端通过第二终端向第一网络设备发送数据时,由于第二终端尚未完成中继数据的配置,因此不能对该数据进行转发的情况,在一种实现方式中,第二终端可以在完成中继数据的配置或者在接收到第二RRC重配置消息后,指示第一终端可以通过第二终端进行上行传输,在这种情况下,方法400还可以包括步骤405:第二终端向第一终端发送第五指示信息,第五指示信息指示第一终端通过第二终端进行上行传输。
在另一种实现方式中,第一网络设备可以在接收到来自第二终端的第二RRC重配置完成消息后,指示第一终端可以通过第二终端进行上行传输,在这种情况下,方法400还可以包括步骤406:第一网络设备向第一终端发送第六指示信息,第六指示信息指示第一终端通过第二终端进行上行传输。
可选地,作为一种实现方式,如果第一网络设备仅向第二终端发送第二配置信息,换句话说,第一终端没有收到第一配置信息,也即第一终端没有收到指示第一终端对第一通信链路的信号质 量进行测量的配置信息,则当第一网络设备后续需要释放第一终端的中继链路时,第一网络设备还可以向第一终端发送用于指示第一终端对第一通信链路的信号质量进行测量的配置信息,否则第一终端设备无法进行移动性管理。
例如,当第一网络设备决策释放第一终端的中继链路时,第一网络设备可以给第一终端发送用于释放第一终端在中继链路上传输数据所需要的配置信息,和/或,用于第二终端为第一终端提供中继服务所需的配置信息。此外,第一网络设备还可以向第一终端发送用于指示第一终端对第一通信链路的信号质量进行测量的配置信息,可选地,用于释放第一终端在中继链路上传输数据所需要的配置信息可以和用于指示第一终端对第一通信链路的信号质量进行测量的配置信息可以承载在一条消息中发送至第一终端。
相应地,若第一网络设备仅向第一终端发送第一配置信息,则第一网路设备在释放第一终端的中继链路时,还需要给第二终端设备发送用于指示第二终端对第二终端与第一网络设备之间的通信链路的信号质量进行测量的配置信息。
